When the digestion and absorption of carbohydrates result in more energy-rich molecules than are immediately required by an anim
al, the excess is: a) stored as glycogen in the liver and muscles. b) hydrolyzed and converted to ADP. c) eliminated in the feces. d) oxidized and converted to ATP. e) stored as starch in the liver.
Glycogen is the stored form of glucose in animals. Digestion of carbohydrates breakdown the complex sugars into simple sugars, mainly glucose. These simpler sugars are carried to cells to serve as respiratory substrates. The excess of the simpler sugars is taken up by the cells of the liver and muscles and is stored in the form of glycogen.
Glycogen storage in liver and muscle cells serves as a source of glucose as and when required. The large cytosolic granules of glycogen consist of glycogen and the enzymes required for its synthesis and breakdown. The synthesis of glycogen from glucose is called glycogenesis.
sepals protect inner floral leaves in bud stage of the flower, carry out photosynthesis, attract animal pollinators when petaloid (have same color with petals eg in pride of barbados)
Nucleoside analogs are the mutagenic chemicals that have a structure that is similar to the normal bases of the nucleotide and thus can be incorporated in the DNA during the process of replication, however as it has different base-pairing rules than the normal nucleotide base it can lead to mutations.
An example of a nucleoside analog is acyclovir which an analog of guanosine.
